Chemical Modification of Polyester Fibers with Amide-Siloxane Film and its Antimicrobial Property by Electro-Less Silver Plating
Antibacterial polyester (PET) fibers with high electric conductivity were introduced by pretreatment-free electro-less silver plating in this study. The PET fibers were modified with the amide-siloxane film before silver coating, which was proved by the ATR-FTIR spectra, energy dispersive X-Ray (EDX) analysis and thermo-gravimetric (TG) analysis, respectively. Uniform and compact silver-coated film was found on the surface of PET fibers, evidenced by scanning electron microscopy (SEM). With 16% silver loading, the results indicted that silver-coated fibers have high electric conductivity (2.66Ω/cm) and exhibit strong antimicrobial activity against Escherichia coli (with 6.5 mm inhibition ring).
